Undifferentiated Pancreatic Carcinoma With Osteoclast-Like Giant Cells: What Do We Know So Far?

Undifferentiated carcinoma of the pancreas is an aggressive but rare tumor for which several other terms have been used to describe its histological appearance. In addition, as osteoclast-like giant cells may accompany undifferentiated carcinoma of the pancreas, the WHO Classification distinguishes undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) from plain undifferentiated carcinoma since there are a few histopathological and clinical differences. UC-OGC was initially thought to be associated with worse prognosis compared to invasive ductal pancreatic adenocarcinoma, since it is often unresectable at diagnosis and tends to recur rapidly even if completely resected. When true UC-OGGs are carefully dissected out from other anaplastic carcinomas, it becomes, however, clear that UC-OGCs do have more indolent behavior, especially the pure UC-OGCs. This mini-review summarizes the current knowledge on UC-OGC.

A Surgical Alternative in the Treatment of Recurrent Diaphragmatic Hernia after Total Gastrectomy.

Treament of hiatal hernia remains a challenge for surgeons. The techniques for treatment started with cruroplasty, which was later associated with extensive mobilization of the esophagus, with or without fundoplication. Other solutions included the use of synthetic or biological mesh and autologous tissue reinforcement. Despite these therapeutic strategies, the recurrence rate for hiatal hernia is significant, and no existing treatments have had much success in reducing this rate. Total gastrectomy, as in this case, represents an additional challenge because of the absence of gastric tissue, which can buttress the pillars' repair. This case report introduces a novel approach for the treatment of recurrent hiatal hernia, using a pedicled vertical rectus abdominis myocutaneous flap.

Pilonidal sinus destruction with a radial laser probe: technique and first Belgian experience.

BACKGROUND: The treatment of pilonidal sinus disease still remains challenging. Despite many non-surgical and surgical methods, no consensus emerged for the best treatment. We describe a new innovative technique consisting in the destruction of the pilonidal cyst with a radial laser probe (FILACTM, Biolitec, Germany). The energy delivered causes the destruction of the sinus epithelium and the simultaneous obliteration of the tract. METHOD: In December 2015, we retrospectively studied the data of our 40 first patients operated with this technique between September 2014 and September 2015. The mean follow-up period was 234 days (92-316). There were 33 men and 7 women. The mean age of the patients was 25.2 years (15-46). RESULTS: The success rate was 87.5% (35 patients/40). Recurrence rate was 2.9% (1 patient/35). Hospital stay was 1 day for all the patients with no re-hospitalisation during the follow-up. The mean duration of soiling before healing was 18.6 days (2-35). The mean duration of pain-killers intake was 4.9 days (0-14). Four patients presented complications: 2 hematomas (5%) and 2 abscesses (5%), all medically treated. CONCLUSION: The destruction of a pilonidal cyst with a laser probe is a safe, simple and minimally invasive technique. The success rate is good. Hospital stay is short, pain is light and complications are few as well as the number of patients needing post-operative care, allowing a rapid return to work or school. This technique could be proposed as a first-line treatment to the majority of patients with a pilonidal sinus disease.

Single port access laparoscopic cholecystectomy (with video).

BACKGROUND: Single port access (SPA) surgery is a rapidly evolving field due to the complexity of NOTES (natural orifice translumenal endoscopic surgery). SPA combines the cosmetic advantage of NOTES and possibility to perform surgical procedure with standard laparoscopic instruments. We report a technique of umbilical SPA cholecystectomy using standard laparoscopic instruments and complying with conventional surgical principle and technique of minimally invasive cholecystectomy. METHODS: Preliminary, prospective experience of SPA cholecystectomy in 11 patients (median age, 46 (range, 27-63) years) scheduled for cholecystectomy was evaluated. Diagnoses for cholecystectomy were: symptomatic gallbladder lithiasis (n = 7), previous acute cholecystitis (n = 3), and biliary pancreatitis (n = 1). RESULTS: SPA cholecystectomy was feasible in all patients (median body mass index, 24 (range, 20-34) kg/m(2)) who were scheduled for preliminary experience using conventional laparoscopic instruments. Median operative time was 52 (range, 40-77) minutes. Intraoperative cholangiography was performed in all patients, except one, and was considered normal. No peroperative or postoperative complications were recorded. Median hospital stay was less than 24 h. CONCLUSIONS: SPA cholecystectomy is feasible and seems to be safe when performed by experienced laparoscopic surgeons using standard laparoscopic instrumentation. SPA cholecystectomy may be safer than the NOTES approach at this time. It has to be determined whether this approach would benefit patients, other than cosmesis, compared with standard laparoscopic cholecystectomy.
